4 1. Context for water allocation and reallocation

5 Jurisdiction for water legislation, policy making and watershed management in Spain European Union Central government Autonomous regions Municipalities Treaties, Regulations, Directives, Case law (European Court of Justice) Environmental quality, agriculture, nature protection, water quality Spanish constitution, laws, regulations & decrees Water planning and management of inter-regional river basins Agricultural policy, land use policy, environmental policy Water legislation, planning and management in intraregional river basins Urban supply and sanitation Urban land use planning & waste management

6 The challenge to harmonize national water legislations at the EU level The EU is not a Federation: 28 member states with different political, legal and cultural traditions The USA: 58 federal states with a common Constitution, shared sense of nation and legal tradition. The United States

7 The challenge of coordination at the national level River basin management since the 1920s (evolving goals, methods actors and discourses) Decentralized quasi-federal political-administrative organization since the late 1970s 17 Autonomous regions and 14+7 overlapping river basin districts Division of authority regarding water management between central and regional governments is a contentious and ongoing process.

12 Administrative mechanisms for water allocation Spatial scale Characterization Legal/administrative instrument Dominant allocation criteria International Spain shares four major river basins with Portugal (40 % of country s territory) Albufeira Convention Guarantee hydroelectric production, water supply, flood protection and environmental flows. Country Allocation of water resources among river basin districts National Hydrologic Plan National hydrological balance for economic and territorial strategies River Basin District Allocation of water to different users Basin Hydrologic Plan Regional economic and sectoral development. User Holder of water use rights Water use permits (concessions, private groundwater rights, historical irrigators) Existing rights

13 Water rights (concesiones) Water is a public good, the hydraulic public domain Water permits (concesiones) grant use rights for up to 75 years for a specific use in a specific location Long licensing periods limit management flexibility and create a sense of private property over water Restrictions and administrative reallocation takes place in times of drought and to guarantee domestic water supply (agreed upon in user-participated Management Boards at the river basin scale) Water use permits often pre-date the introduction of environmental concerns in water management Permit review processes (for environmental, socioeconomic, scarcity or efficiency reasons) are politically challenging, potentially expensive, and seldom undertaken

14 Informal water markets in Spain Informal water markets Public water banks Water use permit trading River basin district Annual volumes traded (Mm 3 ) Volumetric prices ( /m 3 ) Segura 25 -?? M. Andaluzas 30 -?? Júcar Trading concentrates in southeastern Spain: highest socioeconomic scarcity and very profitable water-dependant activities (irrigation and tourism). Private contracts between users that are sometimes approved by the water administration. A majority of contracts take place between irrigators and between irrigators and urban water users. There is scarce information on volumes exchanged or prices paid. Prices often exceed official rates for water & show ability to pay/scarcity value.

15 2. Triggers, characteristics and evolution of water markets

16 Triggers for the introduction of water markets in Spain Evolution of mean precipitation between 1920/21 and 2000/2001 mm / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / hm 3 SOCIOPOLITICAL CONSENSUS Widespread agreement that water markets could serve as a tool to transform the dominating hydraulic water management paradigm in Spain. Help prevent water restrictions in urban areas near irrigation districts in times of drought, Offer an alternative to interbasin water transfers between distant regions as a solution to local water shortage problems, thus avoiding the high political, socioeconomic and environmental costs of these transfers

17 Highly regulated and publicly controlled water markets: 1999 Water Act reform Water use permit trading Private contract between water permit holders Buyer and seller must be within the same river basin district Contracts are temporary (no permanent reallocation) Contracts must respect order of priority allocation (lower to higher) Non-consumptive users cannot sell to consumptive users Only volumes effectively consumed can be traded Public water banks Established by River Basin Authorities (RBA) under exceptional circumstances RBAs publish an offer to purchase (temporarily or permanently) water use permit rights at a pre-established price The purchased rights can be held by the RBA (for environmental reasons or to increase supply guarantee) or reallocated to other users

18 Water inflows to the Tajo river headwater reservoirs and volumes transferred 2500 Mm³/year 2000 Mm³/year 1500 Mm³/year Mm³/year 47% Stream flow entries Volume transferred 1000 Mm³/year 500 Mm³/year 764 Mm³/year 348 Mm³/year 0 Mm³/year

19 Liberalization of water markets: The Drought Decrees and the 2013 reforms Content and justification for the reform Incorporate pre-1985 irrigation water rights into market mechanisms Allow use of interbasin water transfer infrastructures for interbasin water permit sales Very limited use of existing market mechanisms for water reallocation (less than 1% of total consumed water but more significant in some regions) Water trading in different river basins in 2007 (Mm 3 ) River basin district Intra-basin permit sales Inter-basin permit sales Public water banks Volume traded/total consumption (%) Guadalquivir Tajo Segura 2, M. Andaluzas 0, Up to 30% of volumes transferred Júcar Guadiana

20 3. Lessons learned

21 Water markets The introduction of markets implies changes in the relative value assigned to market versus political deliberation for the management of natural resources. Legally prescribed water trading mechanisms are infrequently used under normal hydrological conditions for a variety of reasons (reluctance of users, legal constraints, etc.) Existing information indicates that the most significant volumes of formal water trading use interbasin transfer infrastructures in times of drought to avoid legal limits (and political outfall) of transfer decisions. In the case of Spain the progressive liberalization of market instruments responds to a desire to substitute politically contentious transfers decisions by purportedly apolitical, value-neutral and efficient market mechanisms. Informal water trading continues in many water-stressed regions and serves to resolve local problems of scarcity. However, the lack of administrative supervision fails to defend the public interest.

22 Some pre-conditions for the introduction of water markets Incorporated into broader basin management plans. Clearly defined, solid and stable institutional context Clear goals (environmental improvements, reduced social conflict, prevent drought-related losses, reduce water scarcity...) Transparency with regard to market characteristics and operation (contracts, actors involved, characteristics of the permits traded, volumes traded, price, location, temporal scale, etc.) Clearly delineated "boundaries : existing permitted uses, volumes effectively used, geographic scale, etc. Constant evaluation of socioeconomic, environmental, territorial impacts, BUT not aggregated, instead geographically distributed Public scrutiny of its selection, design, implementation and evaluation.
